TOOL-HANDLE.

SPECIFICATION forming part of Letters Patent No. 364,097, dated May 31,1887.

Application filed September 20, 1886. Serial No. 214,365.

(No model.) Patented in England August 13,1885, No. 9,649; in Aus tria-Hungary October 17, 1885, No. 27,813 and No. 54,887, and in France October 20, 1885, No. 169,776.

To aZZ whom it may concern.-

Be it known that I, J OHANN GEORG FISCHER, a subject of the King of Bavaria, residing at Augsburg, in the Province of Schwaben, Neuburg, and State of Bavaria; in Germany, have invented a new and useful Iniprovement in Tool-Handles, (for which I have obtained a patent in Great Britain on date of -August 13, 1885, under No. 9,649; in Austria,

on date of October 17, 1885, under-No. 27,813; in Hungary, on date of October 17, 1885, under No. 54,887, and in France, on date of October 20, 1885, under No. 169,776,) of which the following is a specification.

The want of a practicable combination to fasten little instruments with accuracyv and facility in their handles was heretofore perceptible in a disagreeable fashion to all mechanicians and other craftsmen, because on account of the several forms and thicknesses of instruments a straight central fastening of small instruments has not been possible without a tool-holder in the handle. A correct fastening must absolutely be necessary not only for making exact objects,but also for the preservation of the instruments. I have met the said want by the following described toolholder, which now effects the'mentioned instrument-fastening in a convenient fashion. I attain this fastening by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the toolholder fixed in the handle by being driven or pressed into the recess. Fig. 2 shows the toolholder withdrawn from the handle by pressing together or gripping the two flat sides and opened by turning the two parts of which it is composed on the joint. Fig. 3 is a top view of the tool-holder in the closed position.

Similar letters refer to similar partsthr'oughout the several views.

' The tool-holder consists of two parts, A A, turning on a joint, e, each part being provided with a recess, B, (of a squared or rectangular section,) for gripping the tool.

The tool-holder is made of metal and may be applied to allikinds of handles, all that is required for this purpose being the provision of a suitable recess, B, therein.

and the tool is fixed in a straight central position, its attachment and removal being rapidly effected.

At the upper end of the tool-holder shoulders O are provided ,which,receiving the pressure of the handle, press together the two halves A A when the holder is driven into the handle H.

The taking out of the tool-holder may be ef- By these k means the instrument is permanently fastenedfected by seizing it with pinchers at the shoul-.

the jaws in a direction parallel with the sides in which the recesses are cut, so that the jaws swing away from and not over each other, all,

substantially'as described.
